Abell 23 Planetary Nebula

Imaged on nights of 2021/3/3, 2021/3/5, 2021/3/6

Abell 23 (PK249.3-5.4) is an almost never imaged planetary nebula in Puppis. This is only the third image on Astrobin. Abell23 is a small Abell, measuring 0.9 arc minutes and has a magnitude listed at 13.1. There is only the slightest hint of it on the RGB image. The Oiii signal is much stronger than the Ha signal. However, the Ha emission shows as a strong outer ring surrounding the Oiii, perfectly circular. A lovely and striking combination.

This Abell was a particular challenge for me because it transits at 19 degrees at my observatory in Taos, NM. This required 3 nights of imaging and many poor subs discarded. Well worth the effort though. It has some interesting detail.

Currently 60+, and soon to be complete.

This is everything I could find on the web about this PN. Very obscure.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
